D. OROAKE. BUNG RETAINER AND STAMP PROTECTOR.

No. 391,455. Patented Oct. 23, 1888.

NITED STATES BUNG-RETAINER AND STAMP-PROTECTOR.

SPECIFICATION forming part of Letters Patent: No. 391,455, dated October 23. 1888.

Application filed March 19, 1888.

T 0 aZZ whom it may concern.-

Be it known that I, DANIEL CROAKE, of Milwaukee, in the county of Milwaukee and State of \Visconsin, have invented new and useful Improvements in Bung-Retainers and Stamp- Protectors; and I do hereby declare the following to be a full, clear, and exact descrip tion of said invention, reference being had to the accompanying drawings, and to the letters or figures of reference marked thereon, which form a part of this specification.

My new bung-retainer and stamp-protector, the novel features of which will be hereinafter distinctly claimed, is an improvement upon the bung-retainer patented to me on October 4, 1887, No. 370,857, which improvements I have found it necessary to devise to obviate more expensive and unreliable devices contained in that bung-retainer.

In the drawings. Figure 1 is a perspective view of the under side of the plate of my improved bungretainer in the process of con struction immediately after the apertures have been made for the retaining-staples. Fig. 2 1s a perspective view of the under side of the bung-retainer immediately after the staples have been inserted. Fig. 3 is a view of one of the staples. Fig. 4 is a vertical transverse section of my completed bung-retainer on line X X of Fig. 5. Fig. 5 is a perspective view of the completed bungretainer.

The same letters refer to like parts in'all the figures.

The plate A is a strip of sheet metal, preferably of tin, having two sets of apertures, B B, punched through the plate, one set near each end of the plate. The punch is driven through the plate from the upper side, forming on the lower side downwardly-turned jagged or saw-toothed edges. These apertures are made near the respective ends of the plate, and in proper position to receive the tangs O O of the staple D. The apertures are made slightly smaller than that part of the tangs-O G that is near to the crossbar of the staple. The staple D is affixed to the plate A by thrusting the tangs O 0 through the apertures 13 B from the upper side and forcing the staple Serial No. 267,670. (No model.)

down into the plate until the cross-bar of the staple is set into the plate A under such pressure as to indent the plate and form a groove therein between the apertures B Bat each end. In this groove the crossbar of the staple is fitted so deeply that its upper surface is in a plane with the upper surface of the plate A. At the same time the jagged saw-toothed edges of the plate about the apertures B B are forced inwardly against and slightly into the tangs of the staple, and at the same time the tangs of the staple are spread apart somewhat,as shown in Figs. 4 and 5, whereby the staple is fixed and retained firmly in position in the plate. The spreading of the tangs obviates the possi bility of the staple falling out of or being removed from the plate, even if by any means the edges of the plate about the apertures B B should fail to be sufficient to permanently hold the staple; and the cross-bar of the staple being embedded in the groove in the plate holds the staple against twisting or turning, the whole forming a very strong, reliable, and inexpensively constructed bung-retainer.

A very important and desirable feature of this retainer is that there is no lip or sharp catching-edge on this device on the outside above the surface of the plate either at the points of attachment of the staples or elsewhere.

lVhat I claim as new, and desire to secure by Letters Patent, is

A bung-retainer consisting ofa plate of sheet metal, and two bung-retaining staples inserted therein, one at each end, the tangs of the staples being spread beneath the plate, and the cross-bar of the staple being sunk into the upper surface of the plate, and the jagged edges of the plate about the apertures through which the tangs are inserted being against the tangs of the staples, substantially as described.

In testimony whereof I affiX my si gnatn re in presence of two witnesses.

DANIEL UROAKE.
